METALLIC FENCING.

SPEGIPICATION forming part of Letters Patent No. 324,221, dated August11, 1885.

Application filed August 12, 1884.

and in such a manner as to effectually secure the fencing against alllongitudinal displacement, while at the same time it may be quickly andeasily removed or detached from the posts without marring or injuringeither it or the fastening-staples; second, to impart additionalelasticity and strength to the fencing, to enable it to withstand thecontraction and expansion caused by changes in temperature, to resistundue strain, and retain its taut and rigid position; third, to providemeans for more nearly equalizing the length of the flat metal strip andthe wire or strand combined therewith.

To these ends my invention consists in the combination, with a flatmetal strip, of a wire lying thereon, and raised at suitable intervalsout of contact therewith by means of an interposed body or device of anysuit able character, whereby (the strip and wire being twistedsimultaneously, causing the wire to follow and substantially lie in theconvolutions of the strip) the length of the wire and the strip is morenearly equalized, and means provided so that the fencing may be firmlystapled to the posts without injury to the strip, and the same removedor detached from the posts with a common tool without marring orinjuring the strip or the fasteningstaples, and an increased degree ofelasticity is imparted to the fencing. This fencing may be provided withbarbs in any desired manner. This may be accomplished by extending theends of the interposed body or device to a suitable distance and formingtheir extremities into barbs. The fiat metal strip may be ribbed orcorrugated.

Fig. 9 is a front elevation-of the parts shown in Fig. 8.Fig. 10 is a view of a section of fencing, showing the manner ofutilizing the ends of the interposed body or device to provide thefencing with barbs. Figs. 10, 10, 10, and 1O are cross'sections of Fig.10.

In said drawings, the reference No. l indicates a fiat metal stripcomposed of any suit able metallic material. With this strip I combine awire, 2, of any suitable form, running longitudinally therewith, and atsuitable intervals, a body or device, 3, of any proper form andmaterial, is interposed between the wire and the strip, separating thetwo at such points. WVhen the two, provided with an interposed body ordevice, 3, are twisted together, as shown in Fig. 7, the wire is closelydrawn upon the'face of the strip, save at and near those points wherethe interposed body or device 3 occurs, where it will be raised off thestrip and an interval or space left between the wire and the strip. Thusthe wire, while ICQ it follows substantially the convolutions of thestrip, is thrown out of a regular spiral course at intervals, impartinggreat rigidity to the fencing, and giving it an increased degree ofelasticity, enabling it to withstand the contraction and expansionresulting from changes in temperature, as well as strain applied in anydirection, without impairing its taut and rigid condition.

In twisting a iiat metal strip and a wire together the former willshrink in length from torsional contraction more rapidly than the wire,and this inequality is practically remedied by the combination andconstruction mentioned, because, by interpcsing a body or device, 3,between the strip and the wire at intervals and twisting the twotogether, projecting portions are formed in the wire, giving it ineffect a new direction at and near where the interposed body or device 30c curs. This, while adding materially to the elasticity of the fencing,tends to equalize the length of the flat metal strip and wire in thefencing.

The interposed body or device 3 may be composed of any suitablematerial, and have any suitable form, attachment, or application. Forexample. a simple wire coil may be used, as shown in Fig. 1, and thismay be mounted upon or coiled around the wire strand 2, or a wire may hecoiled upon the strip 1, as shown in Fig. 2, with its ends 4 upon theoutside of the strip; and this form of construction may be varied byarranging the said ends so that they shall lie under the wire 2, as seenin Fig. 4, whereby they will be held firmly down, preventing the coilfrom opening or loosening. Again, the interposed body or device 3 may becoiled upon the wire 2 with its ends 5 5 projecting in oppositedirections and lying against the face of the strip, as shown in Fig. 3,whereby a similar purpose is accomplished, the coil being tightenedupon. the wire 2 by the pressure of its ends upon the strip.

Instead of a wire coil, such as is described, a simple body, 6, may beused composed of metal or other suitable material, and having anysuitable form, construction, or application, so to raise the wire 2 oit'the strip 1 at suitable intervals. Again, a wire loop or coil, 7, may beused, having its ends 8 8 projecting in opposite directions crosswise ofthe strip, lying intermediate of the strip and the wire 2, and formingan angle with each other, whereby they have contact with the strip nearits edges only. This gives increased space between the strip and thewire 2 in excess of the diameter of the coil 7, and also gives anelastic hearing or seat, since any strain tending to force the wire 2toward the flat metal strip will be resisted by the elasticity of theends 8 8. Such force will also more firmly bind the coil upon the wire 2by tightening its loop.

The fencing may be applied to the posts in the manner shown in Figs. 8and 9, in which the reference-number 9 indicates the post.

The instances at which the wire 2 is raised oil the strip are of suchfrequency throughout the line of fencing as to bring such points intoengagement with the posts often enough to afford afrequent fastening ofthe kind shown. It consists in stapling upon either side of theinterposed body or device 3, the staple being driven down upon the wire2in close proximity to the interposed body or device 3, and entering farenough to form a shoulder or abrupt bend, 10, in the wire 2. The fencingcannot turn upon the post while the staple is being driven by reason ofthe flat metal strip 1, which lies against the post.

This form of fastening provides a most secure attachment of the fencingto the posts without injury to the strip 1. It also wholly avoids anylongitudinal displacement of the fencing without the necessity ofembedding it in the posts, which often impairs its strength, and itaffords means for removing the staple without cutting it or injuring thefencing.

Itis well known thata wire will withstand far more bruising and marringwithout substantial. injury to its strength than a flat strip can 9sustain, for if the edges of the latter are once torn or broken itsstrength is destroyed.

The fastening may be applied, as shown, at points where the raised wire2 is presented at the posts, whereby the staple or staples may be drivendown thereon far enough to form a shoulder or abrupt bond, 10, in thewire 2 on either or both sides of the interposed body or device 3. Thisfully protects the strip and gives as strong and secure a fastening ascan be desired.

Where the fencing crosses posts at points where the wire 2 is lying uponthe strip, a staple may be driven in lightly over the fencing, whichwill afford suilicient fastening at those points.

Having thus described my invention, what I claim is-- l l. Thecombination, with a flat metal strip and a wire twisted together, of asuitable body or device coiled around or mounted upon the wire or thestrip, whereby the wire and strip are separated at such point or points.

2. The combination, with a flat metal strip and a wire twisted together,of asuitable body or device coiled around or mounted upon the latter,whereby the wire and strip are separated at such point or points.

3. The combination, with a flat metal strip and a wire twisted together,of a wire looped or coiled around the latter and having its endsextending outward crosswise of the strip and bearing upon it near itsedges only.
